We manufacture steel and stainless steel exhaust silencers according to our customers' projects. As BECA Metal, we offer a service specialized in acoustic silencer manufacturing. We use our engineering capabilities to provide our customers with environmentally friendly, high-performance and customizable acoustic silencers. Acoustic silencers are important components used to reduce and control noise. It is used in various applications from industrial facilities to power plants, from HVAC systems to motorized equipment. We determine the dimensions, materials and features in accordance with the needs of our customers.In the silencer manufacturing process, we provide effective sound insulation by using high quality acoustic materials.

Evolution 15W/40 SN/CF is a top-tier engine oil that adheres to the stringent API SN/CF standards. This high SAPS (Sulfated Ash, Phosphorus, and Sulfur) and ACEA A3/B4-rated lubricant delivers superior engine protection by significantly enhancing oxidation resistance. It is designed to cater to a wide range of gasoline, diesel, and LPG four-stroke engines commonly found in passenger cars and trucks, especially European models lacking catalytic exhaust systems. Whether your vehicle faces extreme or varied operating conditions, this oil is the ideal choice, particularly in professional workshop settings. One notable feature of Evolution 15W/40 SN/CF is its incorporation of Group III base oil, which effectively combats engine oil oxidation. This, in turn, offers heightened protection against piston deposits, surpassing the performance of standard SN engine oils.

This sensor for measuring exhaust gases was developed together with a Formula 1 team. The goal was to achieve the greatest possible reliability during the race. The sensor was designed so that it can withstand a maximum of vibrations and extreme temperatures while being made in a highly compact construction at the same time. The special feature is the connection lead. It is not made from the usual mineral-insulated stainless steel sheathed line, which is too rigid and which tends to vibration fractures. Instead, the line is made of stranded conductors with PTFE insulation and an additional heat shield so it can be easily and flexibly adapted to the environment. The sensor is being used with exceeding success by professional teams in long distance races, American race series and the domestic DTM. The benefits: Highly vibration-proof Very robust High temperature resistance (up to 1,200 °C) Individual plug assembly possible Can be individually adapted
